   Tesla and SpaceX begin construction on Terafab semiconductor plant in Texas

   Tesla and SpaceX have started erecting structural steel for Terafab, a massive advanced technology chip fabrication facility in Grimes County, Texas. Designed to be the largest building on Earth, the project aims to produce AI chips. Reports on the facility's scale vary, with some sources citing a 100 million square foot footprint stretching 3 miles, while cost estimates range from $16.8 billion to $119 billion. The project has already prompted Korean equipment suppliers like HPSP and Hanmi Semiconductor to secure their supply chains in anticipation of orders.

   Why it matters

   The facility represents a strategic move by Elon Musk to reduce reliance on external chip manufacturers for AI hardware. By building a dedicated fab, Tesla and SpaceX intend to integrate chip design and production. This shift could alter the global semiconductor supply chain.

   What is confirmed

   • Tesla and SpaceX are collaborating on the Terafab semiconductor facility.
   • The Terafab plant is located in Grimes County, Texas.
   • Construction has progressed to the erection of structural steel.

   Still unconfirmed

   • The project costs $119 billion.
   • The project costs $16.8 billion.
   • The building will cover 100 million square feet.
   • The structure will stretch 3 miles in length.
   • The project costs £90 billion.
   • Work was scheduled to start in December.

   What to watch next

   • Confirmation of final project budget and total square footage
   • Official production timelines for the first AI chips
   • Formal procurement contracts with Korean chip equipment suppliers
